Function arrayfire::approx2_v2

pub fn approx2_v2<T, P>(
    output: &mut Array<T>, 
    input: &Array<T>, 
    pos0: &Array<P>, 
    pos1: &Array<P>, 
    method: InterpType, 
    off_grid: f32
) where
    T: HasAfEnum + FloatingPoint,
    P: HasAfEnum + RealFloating, 

Same as approx2 but uses existing Array as output
